G-A S-BURNER Specification of Letters Patent.

Patented. July 27, 1909.

Application led December 5, 1907. Serial No. 405,272.

To all whom it may concern:

Be it known that I, JOSEPH HENRY AT- WOOD, a citizen of the UnitedStates, residing at Empire City, in the county of Cherokee and State ofKansas, have inventedcertain new and useful Improvements in Gas-Burners;and I do declare the following to be a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in gas burners for uprightboilers.

The objectof the invention is to provide a burner of this character bymeans of which the boiler iiues or tubes will be uniformly heated and aminimum amount of gas used for supplying the heat.

With this object in view, the invention consists of certain novelfeatures of construction, combination and arrangement of parts as willbe described hereinafter and particularly pointed out in the appendedclaim.

In the accompanying drawings, Figure 1 is a vertical sectional viewthrough a portion of the boiler, showing the application of theinvention; Fig. 2 is a horizontal sectional view of the same, showing atop plan view of the burner; Fig. 3 is a vertical sectional view of theburner removed from the boiler; and Fig. 4 is a plan view of the burnerhead, partly in section.

In the embodiment of the invention I provide a hollow burner head 1,which may be of any suitable shape but which is here shown and ispreferably of a fiat cylindrical form. To the lower side of the head, 1,is connected a gas supply pipe, 2, in which is arranged a regulatingvalve, 3. Around the edge of the head 1 is formed a series of radiallydisposed eXteriorly threaded nipples, 4, through which the gas passesfrom the head 1.

Adapted to be screwed into engagement with the nipples 4 is a series ofT couplings, 5, into the outer ends of which is screwed a series ofburner tubes, 6. The right-angular branches, 7, of theT couplings 5 areadapted to project through apertures formed in the bottom of the boilerand serve as air inlet passages, `by means of which air is admitted tothe burner tubes, where it mixes with the gas, thereby providing for agreat saving of the latter and forming a` perfect fuel. The

draft or force of the air in passing through the burner tubes causes theflame to be directed outwardly toward the sides of the boiler, afterwhich the flame is drawn inwardly again by the action of the draftthrough the centrally disposed smoke outlet formed in the top of theboiler. rlhe flame, when thus directed will be distributed evenly overthe boiler iues or tubes, and the heat therefrom will be uniformlydistributed, thus providing for the heating of all parts of the boileralike.

There may be any desired number of nipples, 4, and burner tubes, 6, andthe latter are preferably of such length as to extend within a shortdistance of the inner walls o the boiler as shown.

In practice, the burner head is placed directly upon the bottom A of theboiler casing B, and suitable apertures ct are formed in said bottomthrough which the right-angular branches 7 of theT-couplings, 5,project, thus providing for the admission of fresh outside air to theburner tubes, and thereby dispensing with the necessity of the hoodwhich is usually employed for covering the head of burners of thischaracter.y It has been .found in practice that a hood placed over theburner head is objectionable' for the reason that a considerable amountof heat is caught and confined in the hood and the heating capacity ofthe burner thereby decreased. By projecting the ends of the air inletbranches of the T-couplings through the bottom of the boiler casing,fresh air is admitted to the burner and a covering or hood thus madeunnecessary. The engagement of the branches, 7, of the T-couplings withthe apertures in the bottom of the boiler also serves to iirmly hold theburner head against a turning or twisting movement on said bottom, saidT-couplings thus serving the two fold purpose of admitting outside airto the burner without the use of a hood and of holding the burner headin place.

Having thus described my invention, what I claim as new, and desire tosecure by Letters-Patent, is:

In a boiler, in combination, a casing having a bottom, a burner seatedflat on said bottom, a supply pipe connected to said burner through anaperture on the bottom, of a plurality of radially extending nipplesconnected to said burner, T couplings connected to the nipples and eachhaving its right angular end passing through and closely fitting an i Intestimony whereof I have hereunto set aperture in the bottom, and burnertubes ynnyhand in presence of two subscribing Witconnected to the Tcouplings in alinement nesses.
